Detailed Solution

The above statement is True.
A voltmeter is a device that is used to determine the potential difference between two points in an electric circuit, whereas an ammeter is used to determine the current flowing through a circuit.
Basically, a voltmeter is always connected in parallel with devices to measure voltage, whereas an ammeter is always connected in series with a device to measure its current. As in the given circuit diagram, a voltmeter is connected in parallel with a resistor. On the other hand, an ammeter is connected in series with the same resistor. Thus, the above circuit diagram given is correct.
